Instructions

Preheat the oven: Set your oven to 375°F (190°C) to warm up while you prepare the ingredients.
Prepare the chicken: Pound the chicken breasts to 1-inch thickness for even cooking and slice into ½-inch pieces.
Make the marinade: In a large bowl, whisk together fajita seasoning, 3 tablespoons of oil, soy sauce, honey, lime juice, and Worcestershire sauce. Add the chicken slices and coat thoroughly. Marinate for at least 30 minutes, or refrigerate overnight for more flavor.
Prepare vegetables: Line a large baking sheet with parchment paper if you prefer. Place sliced bell peppers and onions on the sheet, drizzle with 2 tablespoons olive oil, salt, and pepper. Toss well to evenly coat, then spread them out in a single layer.
Add the chicken to the pan: Remove excess marinade from the chicken slices to avoid sogginess. Place the chicken pieces in the center of the vegetables on the baking sheet.
Bake & broil: Bake everything in the oven for 20-25 minutes until the chicken is cooked through. For a smoky char, switch the oven to high broil during the last 5 minutes and broil for 2-3 minutes.
Serve: Enjoy your fajitas served as tacos, over a fresh salad, or in a burrito bowl with your favorite toppings.

Notes

Marinate chicken for a minimum of 30 minutes for best flavor, but overnight yields even better results.
If preferred, you can substitute the fajita seasoning with homemade spice mixes or taco seasoning.
Pounding chicken evenly ensures quick and uniform cooking.
Using parchment paper on the sheet pan simplifies cleanup but is optional.
Broiling at the end adds a charred texture typical of traditional fajitas.
Feel free to customize with other bell pepper colors or add sliced jalapeños for extra heat.
